Not that I know of, but that's the beauty of (most things) Linux. mke2fs
is part of the e2fsprogs package; adding a wipe-disk feature wouldn't be
unreasonably complicated. Doing a half-dozen overwrites will slow things
down by a healthy margin, but it could be done with relative ease.
What's the "recommended" overwrite procedure? I have a vague memory of it
involving writing 00 and FF and a few other things, and then some
(pseudo)random data, and an equally vague memory of some DOD standard.
I'll try to search for it later on if I stay awake that long.
